FOOD- IRE SERVATIVE COMPOUND.

Specification of Letters Patent.

Patented Oct. 15,1907.

Application filed May 21,1907. Serial No. 374,882.

To all whom 'it may concern:

lieit known thatLWiLLow WEIR HUGHES, a citizen ol the United States, residing at Los Angeles, in the county of Les Angcles and State of California, have invented a new and useful Food-Preservative Coini The diluted salts are then thoroughly mixed in about the following proportions, viz: I

Potassium chlorid... 30.parts. Potassium phosphate 25 Potassium sulfate.... 4 2. 7

Iron phosphate l0 Sodium phosphate 7 Magnesium phosphate 2 Calcium phosphate .L 2

Calcium sulfate 2 Calcium fiuoridnu 4' Sodium chlorid 4 Sodium sulfate 2' silican... ..L 4

These substances are in' the form of powder and after thorough mixing are in condition for application to meats, iruitsand vegetables by dusting or otherwise applying the preservative over their surfaces. Ii pre-- ferred a watery solution may be made of the preserve tive and the articles immersed in the fluid, but the powdered form is preferred; Undercertain conditions it may be of advantage to administer the preparation to animals hypoderinically or by way of the mouth previous to killing them for the purpose of improving their condition.

The proportions of the ingredients may be changed within certain limitations depending on the chemical constitution of the food product to be treated. Of the many elements known to chemists, but comparatively few of them are found in any large quantity in animal tissue. Analysis shows that oxygen, hydrogen,v nitrogen and carbon however are found in very large quantities in every tissue and make up the larger part of their structure. Forming a part of the number'found in smaller quantities, those mentioned above are among the most important and play a very useful part in restoring deranged tissues to'their normal conditionand 'hence are-chosen as the ingredients of the improved preserving compound Having thus described the invention, what is claimed potash, fluorld of lime, and silica mixed in about the proportion specified. v In testimony that I 1. A food preservative compound comprising the pliesphnte of lime, iron, potash, Budd and magnesia the chlorids claim the foregoing as'my own, I

have heretoafllxed my signature in the presence 0!. two
